My invention relates to improvements in stereotyping castingboxes which are adjusted on a frame of suitable height, so as to be used in a horizontal, vertical, or inclined position,"

and have adjustable bearers, the transverse one of which isheldin place by reversible lugs which can be changed for various sized matv rices.

any desired place,'and the short L supports the bearer B. The lug may be moved back- The lugs are all L-shaped, of metal, and each- Ward or forward the length of the slot, and

may be reversed to give it greater reaching power to hold the bearer B at any placebetween the center and the end of the casting: box, as may be desired.

To operate the machine, place the transverse bearer B to the line of the end of the matrix and adjust the lugs D D, so as to keep it in position; place the bearers B B to the'lines '0f the sides of the matrix, with one end of each against thetransverse bearer, put a sheet of heavy Manila paper over all, and then set on the top H and fasten it down firmly with the box, and it is ready to pour the molten metal into it.
